HDPE ni iki?

HDPE isobanurwa nubucucike bunini cyangwa bungana na 0,941 g / cm3. HDPE ifite urwego ruto rwishami bityo imbaraga zikomeye za intermolecular nimbaraga zikomeye. HDPE irashobora gukorwa na chromium / silika catalizaires, Ziegler-Natta catalizator cyangwa catalizike ya metallocene. Kubura amashami byemezwa no guhitamo neza (urugero: chromium catalizator cyangwa Ziegler-Natta catalizator) hamwe nuburyo bwo kubyitwaramo.

HDPE ikoreshwa mubicuruzwa no gupakira nk'ibikombe by'amata, amacupa yo kumesa, imiyoboro ya margarine, ibikoresho by'imyanda hamwe n'imiyoboro y'amazi. HDPE nayo ikoreshwa cyane mugukora fireworks. Mu miyoboro yuburebure butandukanye (bitewe nubunini bwa ordnance), HDPE ikoreshwa nkigisimbuza amakarito yatanzwe namakarito yatanzwe kubwimpamvu ebyiri zibanze. Imwe, ifite umutekano cyane kuruta ikarito yatanzwe kuko niba igikonoshwa cyarakoze nabi kigaturika imbere (“inkono yindabyo”) umuyoboro wa HDPE, umuyoboro ntuzavunika. Impamvu ya kabiri ni uko bongeye gukoreshwa bemerera abashushanya gukora ibisasu byinshi bya minisiteri. Pyrotechnicien iraca intege ikoreshwa rya PVC mu miyoboro ya minisiteri kuko ikunda kumeneka, ikohereza ibice bya pulasitike kubantu bashobora kureba, kandi ntibizagaragara muri X-ray.
